A data warehouse is a central aggregation of data (which can be
distributed physically); a data mart is a data repository that may
derive from a data warehouse or not and that emphasizes ease of access
and usability for a particular designed purpose. In general, a data
warehouse tends to be a strategic but somewhat unfinished concept; a
data mart tends to be tactical and aimed at meeting an immediate need.
